Method and apparatus, in order to multiple trigger limit values to a device to be applied in a process control system

摘要

A method and devices are disclosed, in order to multiple trigger limit values to a device to be applied in a process control system. An exemplary method comprises monitoring a with the operation of the device is connected to the value of a parameter and receiving an input value indicative to an operating state of the device, wherein a first input value a first operating state and a second input value a second operating condition. When the first input value is received, the value of the parameter via a functional block with a first trigger limit value are compared, and when the second input value is received over the function block with a second trigger limit value are compared and a on the comparison implemented based reaction.
